Yep I got my new iPhone 4 …
and when you’ve been around as long as I have and remember being categorically told in no uncertain terms to charge your new toys fully before use.  That was in the days when cell phones used NiCad and NiMH batteries and it was really deflating to take the new thing out of its shiny box and look at it charging every few minutes in anticipation of actually using it.  Those days have gone now…

Or have they?

The iPhone 4 and most other devices & cell phones now have Lithium Ion batteries  and they’re not affected by  ”battery memory”.  These batteries can actually be damaged if you discharge them too often. Some say that they don’t need to be fully charged as they operate best when you hover between 30-70% charge/discharge.  However the battery meter does need to be set to give an accurate indication of how much battery life you have left and the only way to do that is to fully charge the first time.  If the battery meter starts to give you wildly inaccurate estimations of the time remaining try discharging it fully and recharging it to maximum.  You should need to do this more that once every 3 months or so.  Fortunately my iPhone 4 came fully charged straight out of the box so no waiting for me.  It remains to be seen whether it lasts me through the day and how many times it goes stone cold dead through overuse!
P.S. This is the bit that  am most interested in trying first is – video recording, HD (720p) up to 30 frames per second with audio. Yum!

    Hi, I have a question. When I bought my iPhone 4 it had like 40 % of the battery, so I started sync it with my MacBook and it charged like 90%. (can this affect the batter life or memory) Later on I drain the battery until it marked 1%. I fully charge it for about 13 hours.
    Other question is that if I have like 10% left and I started to charge it for about 30 min can this affect the battery life or something?

    I’ll appreciate ur help. Thanx

    Jst received a new iphone 4, so what i like to is for how long should i charge it for the first time. Some say until its reaches 100% and some say more than 12hours, so, what do you say? Please help.

      Some say nothing happens if you charge your ipod the first time for 12 hours, i personally think that if you can wait for the 12 hour charge cycle, do it and if you have a lot of anxiety for using it, then just start using it straight out of the box.

      I´ve done this with all my ipod’s (have 3 so far) and the battery lasts for more than 10 – 12 hours with Wi-Fi On, and like 2 – 4 days without it.

      Good luck with that.

    I replaced my iphone 4 battery at around 3pm today and it is now 11:30pm and it’s only on 12% is this normal? It is a brand new battery too and I’m just wondering if it should be taking this long to charge?
